Sex chatrooms are chatrooms on the internet where individuals either discuss sex or have sex.
They are some of the most popular internet chatrooms in the history of the world, going back to the computer stations in ancient Roman bathouses, their primary purpose being ways to access a multitude of sex chatrooms.
That, and having online discussions on where would be a good place to invade next.
But, as with ancient Rome, and societies all over the world today, it is a logical extension of our desire to live decadently. And talk about our private parts.
By the way, me, too. God I miss it.
